Which Dried Lavender is Safe to Consume?
The safety of consuming dried lavender is not a simple yes or no answer; it depends heavily on the specific variety of the plant. While most types of lavender are not overtly toxic, the crucial distinction lies between culinary-grade varieties and ornamental or hybrid species. The key difference is the concentration of certain compounds, particularly camphor, which can impart a bitter, medicinal, or soapy flavor and can be harmful in large quantities.
Culinary Grade vs. Ornamental
The safest and most recommended variety for consumption is English lavender (Lavandula angustifolia). This species is prized for its low camphor content and its sweeter, more subtle floral notes. Reputable varieties of English lavender for culinary use include 'Munstead', 'Hidcote', and 'Royal Velvet'.
In contrast, ornamental varieties such as Spanish lavender (Lavandula stoechas), French lavender (Lavandula dentata), and the hybrid Lavandula x intermedia (often called lavandin) contain higher levels of camphor. While a small amount of these might not be acutely poisonous, they can ruin a dish with their strong, medicinal taste. Furthermore, many ornamental lavenders are grown using pesticides or chemicals not intended for human consumption, making them unsafe to eat.
Potential Health Benefits of Consuming Dried Lavender
Beyond its use as a flavoring agent, lavender has a long history in traditional and modern herbal medicine. While much of the recent research focuses on essential oils or supplements, the dried flowers are also consumed for their potential therapeutic effects.
- Anxiety and Depression Relief: Some studies on oral lavender oil supplements have shown comparable effects to certain anti-anxiety medications. The act of drinking a warm, lavender-infused tea can also provide a calming, soothing effect.
- Improved Sleep: Lavender is widely known for its calming and sedative properties, which can help reduce insomnia and improve overall sleep quality. Drinking lavender tea before bed is a common practice for relaxation.
- Digestive Health: Traditionally, lavender has been used to alleviate digestive issues such as bloating, gas, and indigestion. It may help stimulate the production of digestive juices.
- Antioxidant Properties: Lavender contains several phytochemicals with antioxidant properties, which can help protect the body from oxidative stress.
How to Safely Prepare and Use Dried Lavender
To ensure both safety and a pleasant flavor, proper sourcing, preparation, and portion control are essential when using dried lavender in the kitchen.
Proper Sourcing and Preparation
- Buy Culinary Grade: Always purchase dried lavender specifically labeled as "culinary grade" or "food grade" from a reputable supplier. This ensures it is the correct variety and has not been treated with harmful pesticides.
- Use Sparingly: The flavor of dried lavender is potent and can easily overwhelm other ingredients. Most recipes call for only a very small amount, typically 1/4 to 1/2 teaspoon of dried buds per recipe.
- Clean and Prepare: Before use, you may want to rub the dried buds gently in your hands or a mortar and pestle to release more of their flavor.
- Infuse for Subtlety: A popular method is to infuse the flavor, rather than adding the buds directly. This can be done by infusing liquids like milk, cream, or honey, or by creating a lavender sugar.
How to Cook and Bake with Lavender
- Lavender Tea: Steep a teaspoon of dried culinary lavender buds in hot water for a soothing herbal tea.
- Baked Goods: Add a small amount of finely ground dried lavender to shortbread cookies, scones, or cakes. It pairs particularly well with lemon and honey.
- Infused Syrups: Create a simple syrup with water, sugar, and dried lavender for use in cocktails, lemonades, or iced teas.
- Savory Dishes: Lavender can be a subtle addition to savory recipes, especially in a traditional herbes de Provence blend, or used with roasted chicken or lamb.
Potential Risks and Side Effects
While culinary lavender is generally safe in small culinary amounts, certain risks and side effects are associated with improper use or high doses.
- Digestive Upset: Overconsumption can lead to side effects such as constipation, diarrhea, and headaches.
- Avoid Essential Oils: Lavender essential oil is highly concentrated and should never be ingested directly, as it can be toxic and cause serious adverse reactions.
- Hormonal Effects: Application of lavender oil to the skin in young, pre-pubescent boys has been linked to breast growth in some cases. The safety of oral consumption for children is not well-established.
- Pregnancy and Breastfeeding: There is insufficient reliable information on the safety of consuming lavender during pregnancy or breastfeeding, so caution is advised.
- Drug Interactions: Lavender can cause sleepiness and may interact with sedatives and other medications that affect the central nervous system. It may also interfere with blood pressure medications.

Conclusion
Ultimately, dried lavender is safe to consume, provided it is the correct culinary-grade variety, such as Lavandula angustifolia, and is used in moderation. The golden rule is to always verify the source and label to ensure it is pesticide-free and intended for consumption. Avoid the higher-camphor ornamental varieties, and under no circumstances should you ingest concentrated lavender essential oil. When used correctly, dried lavender is a delightful culinary herb that can add a unique and aromatic dimension to both sweet and savory dishes, as well as a soothing element to herbal teas and infusions. If you are pregnant, breastfeeding, or taking any sedative or blood pressure medication, it is advisable to consult a healthcare provider before consuming lavender.
